To a/ZZ whom t may concern.'

Be it known that i, JOHN M. PFAUDinR, of

Rochester, in the county of Monroe and State "of New York, have invented certain new and usefullmprovementsinLamp-Burners; andl do hereby declare the following `to be a full, clear, and exact description of the same, reference being had to the accompanying drawings,'forming a part of this specification, and

'to the reference-numerals marked thereon.

Illy present invention relates to centraldraft-lamp burners, and has for its vobject to improve the construction and operation of the burner whereby the gases and vapors rising from around the wick-tube maybe more per-` fectly consumed, to improve the construction tional view of a lamp` provided with my improvements; Fig. 2, a side elevation showing 1 indicates the reservoir or oil-pot of the t lamp of any suitable construction, having the vertically-extending air-tube 2. 3 indicates the topfring of the reservoir; 4, the outer wicktube resting loosely upo'n the ringS; 5, the perforated burner-casing having the chimhey-gallery at its upper portion and the chimney-holding springs b'. The upperportion ot the central tube 2 is preferably somewhat more contracted than the lower portion, as shown, and upon its exterior is provided the sleeve or tube 7, rigidly attached and of substantially the same external diameter as the lower portionof the tube 2, so that the wick will slide upon the tubes 2 and 7, and the upper end of the latter is preferably turned in at 8 to form a round shoulder or bead, as shown, slightly above the upper end of the tube 2, said two tubes forming the small gas or vapor chamber or passage 9, The tube 7 isprovided near its lower portion With'a series of apertures 10, which permit the passage of vapors or gases generated in the oil-pot throughthe chamber 9 to the tlarneof the wick. Instead of causing these vapors or gases to pass into the central perforated airdistributer 11 I provide the latter with a contracted portion 11X, which when said distributer is in position comes about opposite the top of the chamber Qat the end of the tube 2, so that these' gases may pass directly into the flame and are caused to impinge directly thereon by the air passing outwardly through the perforations in the distributein As ameans of securing the distributer removably in p0- sition I form upon the inner side of the central air-tube an annular rib 12, which is cut away at one side, forming a recess 13, and se cure to the lower end of said distributer a spring-latch which will engage with the under side of the rib when it is moved down into the tube, but can only be removed by rotating the distributer until the end of the latch is in line with the recess 13. In the present embodiment this latch consists of a spring 14, secu red to one side of the distributer, extending downwardly, then up on the other side, having an engaging shoulder 15 thereon, while the eXtreme end of the spring is provided with an aperture and is guided upon a pin or rivet 16, this constructionenabling me to employ a comparatively-long spring which will readily yield when lthe distributer is pushed into place without requiring the*V use of force, and thereby prevent damage ,to the parts of the burner it constructed of light material.

At the upper end of the distributer is provided a spreader-plate 17, formed integral with or seperately attached to it, as shown, said plate extending outwardly over the annular wick-recess between the tubes 4 and 7.

18 indicates the eXtinguishertube sliding upon the exterior of the tube 4 and capable of a vertical movement on the latter to bring its upper end into contact with the lower edge of the plate 17, as in dotted lines in Fig. 1, said upward movement being caused by a lever 19, pivoted at 2O to the gallery and having its inner bifurcated ends slotted, as shown at 21, for the accommodation of pins 22, arranged on opposite sides of the tube 1S, as shown in Figs. 2 and 3. This tube 1S is guided in its lOO movements by spring-arms 23, provided with projections 24 at their upper ends loosely engaging the outer sides and rigidly secured at their lower ends to a ring 25, which latter is provided with upwardly extending slotted ears 26, as shown in Fig. 2, adapted to be attached to the inside of the perforated casing, the said slots being extended horizontally, so as to cooperate with pins 261 on the casing and form bayonet-joints. The ring 25 and arms 23 constitute a removable extinguisherframe with which the extinguisher-tube may be removedv from the burner-casing.

The outer end of the lever 19 is provided with a removable thumb-piece 191, which when removed permits the passage of the lever through the slot in the casing, and the lower end of the tube 18 is provided with two or more projections 181, adapted to engage vthe ring-frame 25 and prevent the tube moving too far down. The spring-arms 23 bear with an elastic pressure upon the sleeve 18, so as to maintain it in any position of vertical adjustment, but particularly to hold it against .the upper plate 17 when the lamp is extinguished by the vertical movement of the sleeve, and thereby prevent the escape of any smoke or ill-smelling vapor that is usually apparent when a lamp is extinguished and the wick left uncovered.

It will be be noted that the extinguishing attachment, withv the exception of the pivot for the lever, is mounted upon the ring 25, and therefore the device maybe applied to lamps now in use without extensive modification. It will be also noted that the connection between the operating-lever and the extinguishing-tube 18 is a loose one, so that the latter may rock slightly and make a tight joint with the under side of the plate 17, and this accommodation is facilitated by the employment of the yielding arms 23, having the projections 24 at their ends, which frictionally engage with the exterior of the sleeve at the upper portion of the burner.

Vhile I prefer to employ the extinguisher in connection with a lamp having a central perforated air-distributer and to attach the spreader with which the tube 1S cooperates directly to it, it will be understood that the spreader could be attached to another form of support; but in any event it is desirable to lock it in place, so that it is not liable to become displaced when the tube 13 is moved upwardly against it.

Itis not essential that the extinguishing device described be applied to a lamp such as shown, as it may be applied to any form of lamp having a spreader which will permit the application of the tube or sleeve 18 to the exterior of the wick-tube. The extinguishing-tube 18 may also be used to regulate the iiame of the lamp, if desired; but its principal function is to cooperate with the plate 17 on the distributer to extinguish the fiame and prevent the escape of smoke or disagreeable fumes'.

I claim as my invention- 1. In a lamp-burner, the combination with the outer wick-tube, the central air-tube having an interior projecting portion, and the movable extinguisher-tube,of the air-distribu ter fitting the central air-tube resting on the projection and having the spreader at its upper end with which the extinguisher-tube engages, and vthe spring-catch cooperating with the projection in the central tube for holding the spreader against vertical movement in the tube when engaged by the extinguishertube.

2. In a lamp-burner, the combination with the spreader, of the casing, the removable extinguisher-frame secured therein and separate from the chimney-support, and the extinguishing-tube vertically movable on said. frame.

3. In a central-draft-lamp burner, the combination with the spreader, of the movable extinguisher-tube adapted to cooperate with the spreader, the removable extinguisherframe separate from the chimney-support and having the spring-arms for guiding the extinguisher-tube.

4. In a central-draft-lam p burner, the combination with the spreader, of the burnercasing, the ring removably secured therein having the upwardly-extending spring-arms, said ring being separate from the chimneysupport, and the vertically-movable extinguisher-tube guided by said arms and adapted to cooperate with the spreader.

5. In a central-draft-lamp burner, the combination with the spreader, and the casing, of the ring-frame detachably connected to the interior of the casing,having the upwardlyextending arms, the vertically-movable extinguisher-tube guided by said arms, and the lever having a loose connection with said extinguisher-tube for operating it.

6. In a central-draft-lamp burner, the combination with the spreader, the casing, and the ring separate from the casing and removably connected thereto and having the springarms, of the vertically-movable extinguishertube guided by the arms and arranged t'o cooperate with the spreader, and the pivoted lever having a loose pivotal connection with the extinguisher-tube for moving the latter vertically.

7. In a central-draft-lamp burner, the combination with the central tube having the annular rib, the distributer therein supported on the rib, having the spreader thereon, and the detachable connection between said tube and distributer, of the extinguisher-tube surrounding the wick and adapted to cooperate with the spreader and the lever connected thereto and having the outwardly-extending end for moving the tube freely up or down.
